Enhanced Aroma Profiling of Vodka Using Automated Immersive High-Capacity Sorptive Extraction with GC–MS

In this application note, Markes International outlines the advantages of immersive sorptive extraction, using high-capacity HiSorb probes, for the gas chromatography–mass spectrometry (GC–MS) analysis of a wide range of aroma compounds in vodka. Key benefits of this method include full automation on the Centri multi-mode sampling and concentration system, re-collection for repeat analysis of a single sample under different conditions, and selective purging of ethanol.
